DRILL-PRESS VISE.

SPECIFICATION forming part of Letters Patent N 0. 781,285, dated January31, 1905. Application filed June 1, 1904:. Serial No. 210,670.

To all whom it may concern:

Be it known that I, JOSEPH W. KINGAID, a citizen of the United States,residing at Reading, in the county of Berks and State of Pennsylvania,have invented new and useful Improvementsin Drill-Press Vises, of whichthe following is a specification.

' X of Fig. l.

- therein.

This invention relates to improvements indrill-press Vises; and theobject is to produce a device whereby an article to be operatedon may berigidly gripped and securelyheld and one in which all play may bereadily taken up, thus insuring a solid and secure grip of the jaws onsaid article.

To this end my invention consists in the details of construction, ashereinafter more fully set forth in the following specification andillustrated in the accompanying drawings, in which- Figure 1 is a planView of my device. Fig. 2 is a longitudinal sectional View through XFig. 3 shows the under side of the pawl-block.

Referring more particularly to the drawings, .the numeral 1 indicatesthe base, and this is formed with a flange 1 along both sides, by meansof which it may be secured in any suitable manner to the bed-plate of adrillpress or other machine in connection with which it is desired touse it. This base is provided with a smooth upper face and has anuprightfixed jaw 2 at one end thereof, formed integral therewith, andalso a rectangular central opening 3. Along the inner walls of thisopening 3 I arrange ratchet teeth 1.

The numeral 5 indicates a movable jaw adapted to slide upon the smoothsurface of the base 1 and is formed with a depending reduced portionadapted to enter the opening 3 Back of said movable jaw and alsoslidably arranged upon the base 1 is a block 6, also provided with adepending reduced' portion entering the opening therein. This block isprovided with two spring-actuated these pawls normally in engagementwith said teeth, and each of said pawls is formed with a vertical pin 9,extending upwardly through slots arranged in the block for that purpose.These pins extend for some distance above the base of the block 6 andserve as handles whereby the pawls may be released from engagement withthe ratchet-teeth 1. To move the block, it is necessary to compressthese pins 9that is, to press each toward the longitudinal centerthusdrawing the come sponding pawl out of engagement with the teeth a andpermitting the, block to be moved -Havi'ng thus fully described myinvention,

what Iclaim, and desire to secure by Letters Patent, is

"Ina drill-press vise the combination with a base provided with a smoothupper face and a fixed jaw formed integral 7, therewith, an opening insaid base and a series of teeth on the side walls of said opening, amovable jaw sliding on the upper face of the base and having a dependingreduced portion entering the opening, a block resting on the base, saidblock being 'also' provided with a depending reduced portion enteringthe opening, springpress'ed pawls mounted in each of the side walls ofthe reduced portion of the block and adapted to engage the teeth, saidpawls standing directly below the base of the block, upwardly-projectingpins carried by the pawls, said pins passing through slots in the blockand extending some distance above the base thereof whereby said pawlsmay be released and a screw passing through the block and adapted toengage the movable jaw.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. 7 r JOSEPH W. KINCAID.
